Title:
FIBER-REINFORCED COMPOSITE MATERIAL AND METHOD FOR PRODUCING PREPREG
Document Type and Number:
WIPO Patent Application WO/2022/004586
Kind Code:
A1
Abstract:
This fiber-reinforced composite material: has a resin layer sandwiched by reinforcing fiber layers; has a portion in which electroconductive particles having a sphericity of 85% or greater are disposed in the resin layer, and in which the reinforcing layers at the top and bottom are joined via one of the electroconductive particles; and has a portion in which the electroconductive particles sink into the reinforcing fiber layers. Provided is the fiber-reinforced composite material having sufficient electroconductivity in the direction of thickness thereof, with only a small amount of electroconductive particles added thereto.
